What side effects are associated with this type of intervention?

The most common treatments for ovarian tumors, particularly those involving PARP inhibitors like Niraparib, are associated with several side effects. Niraparib can cause hematologic toxicities such as anemia, thrombocytopenia, and neutropenia. Other side effects include fatigue, nausea, and hypertension. Chemotherapy agents like carboplatin and paclitaxel, often used in combination, can lead to neuropathy, alopecia, and gastrointestinal disturbances. Targeted therapies, such as bevacizumab, may result in hypertension, proteinuria, and increased risk of thromboembolic events. It is important for patients to discuss these potential side effects with their healthcare provider to manage and mitigate them effectively.

What prior FDA approvals exist?

The FDA has approved several PARP inhibitors for the treatment of ovarian tumors. Niraparib, a PARP inhibitor, is approved for maintenance therapy in patients with recurrent ovarian cancer who have responded to platinum-based chemotherapy. Other PARP inhibitors include olaparib and rucaparib. Olaparib is approved for maintenance treatment in patients with BRCA-mutated advanced ovarian cancer after response to platinum-based chemotherapy, and rucaparib is approved for the treatment of patients with BRCA-mutated ovarian cancer who have been treated with two or more chemotherapies. These approvals highlight the role of PARP inhibitors in managing ovarian cancer, particularly in patients with specific genetic mutations or those who have responded to prior treatments.

What other types of research exist?

Promising alternatives to Niraparib for ovarian tumor patients include Olaparib and Rucaparib, both of which are PARP inhibitors with demonstrated efficacy in clinical trials. Additionally, combination therapies involving PARP inhibitors and other agents, such as Cediranib with Olaparib, have shown potential. Investigational treatments like heated intraperitoneal chemotherapy (HIPEC) and novel targeted therapies are also being explored.

Summary

This trial tests niraparib alone and with other treatments in patients with ovarian, fallopian tube, or primary peritoneal cancer. It aims to see if stopping cancer cells from repairing their DNA can help treat these cancers. Niraparib is a medication taken by mouth and is approved for use in patients with recurrent ovarian, fallopian tube, or primary peritoneal cancer who have responded to previous treatments.

Who is the study for?

This trial is for women aged 18 or older with high-grade recurrent ovarian, fallopian tube, or primary peritoneal cancer. They must have measurable disease and be in good enough health to participate (ECOG status of 0-2). Pregnant or breastfeeding women can't join, and participants need adequate organ function and not be on certain medications.

What is being tested?

The study tests the effectiveness and safety of niraparib alone or combined with other treatments like TSR-042, Bevacizumab, Paclitaxel, Carboplatin in treating ovarian cancer. Cohort A focuses on those with recurrent cancer; Cohort C includes newly diagnosed patients.

What are the potential side effects?

Possible side effects include fatigue, nausea, blood cell count changes leading to increased infection risk or bleeding problems. There may also be reactions related to infusions and potential liver issues.

Experimental Treatment

Active Control

Group I: Cohort C: Arm 2: Participants receiving neoadjuvant NiraparibExperimental Treatment2 Interventions

Participants are expected to receive 1 run-in cycle (up to 5 weeks) of carboplatin-paclitaxel during pre-screening. After confirmation that the tumor is HRd, participants will be randomized to three 21-day cycles of neoadjuvant niraparib therapy. After IDS, all participants will receive up to three 21-day cycles of adjuvant platinum-taxane doublet chemotherapy (and optional bevacizumab for participants deemed high-risk; third cycle is optional) followed by niraparib (and optional bevacizumab or bevacizumab biosimilar for participants deemed high- risk) maintenance treatment.

Group II: Cohort A: 1-2 prior lines of therapy (TSR-042, Bevacizumab, and Niraparib)Experimental Treatment3 Interventions

PARP Inhibitor-Naive Platinum-Resistant Ovarian Cancer Treatment Cohort with TSR-042, Bevacizumab, and Niraparib. TSR-042 administered 500 milligrams (mg) on Day 1 every 3 weeks (Q3W) for 4 cycles (each cycle is 21 days), followed by 1000 mg every 6 weeks (Q6W) beginning on Cycle 5 Day 1 until progressive disease (PD) or toxicity. Bevacizumab administered 15 milligram per kilogram (mg/kg) every 3 weeks for up to 15 months. Niraparib 200 or 300 mg per day until PD or toxicity.

Group III: Cohort C: Arm 1: Participants receiving platinum plus taxaneActive Control4 Interventions

Participants are expected to receive 1 run-in cycle (up to 5 weeks) of carboplatin-paclitaxel during pre-screening. After confirmation that the tumor is homologous recombination-deficient (HRd). Participants will then be randomized to three 21-day cycles of platinum-taxane doublet chemotherapy (carboplatin plus paclitaxane). After interval debulking surgery (IDS), all participants will receive up to three 21-day cycles of adjuvant platinum-taxane doublet chemotherapy (and optional bevacizumab for participants deemed high-risk; third cycle is optional) followed by niraparib (and optional bevacizumab or bevacizumab biosimilar for participants deemed high- risk) maintenance treatment.

Other Research

The most common treatments for ovarian tumors include PARP inhibitors, chemotherapy, and angiogenesis inhibitors. PARP inhibitors, such as Niraparib, work by blocking the PARP enzyme, which helps repair DNA damage in cells. This is particularly effective in cancer cells with BRCA mutations, leading to cell death. Chemotherapy, using agents like carboplatin and paclitaxel, targets rapidly dividing cells, causing DNA damage and cell death. Angiogenesis inhibitors, such as bevacizumab, prevent the formation of new blood vessels that tumors need to grow. These treatments are crucial for ovarian tumor patients as they target different aspects of tumor growth and survival, improving treatment efficacy and patient outcomes.
